support non-github plugins

[teto]

I wanted to add https://git.sr.ht/~whynothugo/lsp_lines.nvim to nurr but so far it showcases only github plugins.
I think I found only one case where we could not use a full url instead of the github handles USER/REPO in:
.github/workflows/publish.yml

     - name: Checkout plugin repository
       uses: actions/checkout@v4
       with:
         repository: ${{ matrix.plugin.name }}
         path: .
         fetch-depth: 0

https://github.com/actions/checkout

seems like repository could accept the sr.ht url too. Gonna try

first try at #33

Wild that a proprietary code forge would be required for almost exclusively open source plugins. There should be zero favoritism like short-hands towards any code forge, VCS, let alone the closed source one.

This is not "favouritism". It's convenience because it's a fact that the vast majority of neovim plugins are on GitHub.
Contributions to add support for other sources to NURR are welcome, but comments like this one are not productive and will only ping contributors' inboxes for no useful reason.

@toastal agree with you, yet it's FOSS, people who do the work have the last say. You might want to comment/help with NixOS/nixpkgs#380691 that will remove other providers than github from the vim updater set.
